被調理物を入れる鍋の温度を検知するものである。Conventionally, a rice cooker for cooking unwashed rice of this type has been the same as a rice cooker for cooking normal polished rice. Here, the operation of the rice cooker for cooking the normal polished rice will be described with reference to FIG. The first temperature detecting means is for detecting boiling, and the second temperature detecting means is for detecting the temperature of the pan in which the food is put.

得ることができる。BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is a pan for containing a food to be cooked, a heating means for heating the pan, a first temperature detecting means for detecting boiling, and the pan. Second temperature detecting means for detecting the temperature of the rice, selection means for selecting cooked rice of non-washed rice, and storage means for storing a rice cooking sequence suitable for the non-washed rice cooked in the pan. ,
A control means for controlling the heating means by using outputs of the first temperature detection means and the second temperature detection means as inputs;
When the selection means selects the non-washed rice to cook, the control means cooks the rice according to the rice cooking sequence stored in the storage means. By selecting the cooked rice of the non-washed rice by the means, the rice can be cooked in a rice cooking sequence suitable for the non-washed rice, and the cooked rice can be cooked deliciously. Further, since the heating means can be controlled by the amount of cooked rice, stable cooking performance can be obtained regardless of the amount of cooked rice.

を炊くことができる。According to a second aspect of the present invention, in the above-mentioned first aspect of the invention, the control means extends the time of the precooking step when the selection means selects the non-washed rice. Since the non-washed rice absorbs water more slowly than regular milled rice, extending the time of the precooking process can promote the absorption of water in the precooking process. You can cook well-balanced rice with fluffy grains.

る。According to a fourth aspect of the present invention, in the invention according to the first aspect, when the control means selects the cooked rice of the non-washed rice, the heating power at the time of additional cooking in the steaming step is selected. By strengthening the heating power at the time of additional cooking in the steaming process, it is possible to cook solid rice with less collapse of the grain surface.

おいしく炊き上げることができる。According to a fifth aspect of the invention, in the invention according to the first aspect, the control means eliminates the power-down step and maintains the boiling point when the non-washed rice is selected by the selection means. The non-washed rice has a power-down process, so that the boiling state is calmed down, the inside of the grain is hard, and the rice becomes a poorly cooked rice. By eliminating the process and strengthening the heating power of the boiling maintenance process, it is possible to improve the fire passage of the rice in the boiling maintenance process and cook rice with a well-balanced grain.

定している。Here, a rice cooking sequence stored in the storage means 6 and suitable for non-washed rice will be described. In order to cook the non-washed rice deliciously, the non-washed rice absorbs water more slowly than normal polished rice, so the time for the pre-cooking process to allow the rice to absorb water should be set longer and If the power factor (thermal power) of the down process is low, the rice will be badly heated, so in order to improve the heat factor, the power factor (thermal power) of the power down process is set high enough not to spill out. .

率（火力）を高めに設定している。[0023] Further, since it takes a long time to detect boiling in the non-washed rice, the current-carrying rate (thermal power) in the boiling maintaining step is increased.
Is too high, and the grains tend to crumble, resulting in unbalanced rice. Therefore, set the electrical conductivity (thermal power) in the boiling maintenance process to a low level and reduce the stickiness of the grain surface to improve the fire passage. For this reason, the electricity factor (fire power) during the additional cooking in the steaming process is set to be high.

When rice cooking is started, a precooking step of heating with the first electric power W1 is started. In the pre-cooking step, the heating means 2 is operated when the temperature of the pot 1 detected by the second temperature detecting means 5 is lower than a predetermined temperature θ1, and the heating means 2 is operated when the temperature is equal to or higher than the predetermined temperature θ1.
The temperature in the pan 1 is kept at θ1 while the heating means 2 is on / off controlled so as to stop the operation of.

Further, the time of this precooking step can be changed depending on the type of non-washed rice. The pre-cooking process is terminated after the elapse of a certain time T1, and the cooking process is started by the second electric power W2 where W2> W1.

The power of the power down / boiling maintenance process is set to W1, and if the energization rate of the power down process is low, the cooked rice becomes bad. Therefore, in order to improve the fire spread, the energization rate of the power down process (heating means 2 By setting the ratio of the on time to the off time of) to a value that does not cause spillage, the non-washed rice can be cooked well by the heat. Further, by setting the electric conductivity of the boiling maintaining process to be low, it is possible to prevent the grains from being broken and unbalanced rice due to the excessively high electric conductivity of the boiling maintaining process.

After that, a steaming process is started, and heating (additional cooking) is performed a plurality of times according to the amount of cooked rice during a certain time. By setting a higher energization rate for this additional cooking, it is possible to improve the collapse of the grain surface of the rice and cook the rice firmly.
